I won't try to "sell" you on USAK as I think others up here have done a great job making cases for both companies and everyone has their favorite (and I try not to "troll for business")... I'll just clarify 2 things:

USA Kilts Policy: CUSTOM jackets (colored tweed jackets) are not returnable as they're CUSTOM. Standard Black Argyll jackets / vests (or PC jackets for that matter) ARE returnable as they're NOT custom.

Customs duties to Canada will be similar from either Higgins or us as both jackets would be shipping from the states.

Either way you go, you will be happy with it.
